Use Tax Online Payments

Cook County Purchaser Individual Use Tax customers can remit their payments one of three ways to the Cook County Department of Revenue: by Internet, Phone or Mail.

For all payment types, first complete the Individual Use Tax Transaction form that you received from the Cook County Department of Revenue (DOR), with your assigned Customer Number, then select the payment of choice:

Payments

By Internet – click to the Use Tax Payment Site  to make an online payment with a credit card
(When prompted, use the Provider ID Code - 68011)
By Phone – call 1-888-497-8701 (Provider ID Code - 68011) to make the payment with a credit card
By Mail - mail the completed form and payment to the "Department of Revenue," as noted on the form

If you decide to make your payment before you receive your form from the Department of Revenue with your Customer Number, you may use the downloadable Individual Use Tax Transaction Return form below - but to submit your payment by mail or in person only. All phone and online payments must have the corresponding Customer Number, assigned by DOR, to complete the payment.
